Investigation of Steel Plate Damper with Transverse Slits

Abstract:

This article introduces a new type of steel plate damper with transverse slits. The damper mainly consists of a few parallel core plates, a top plate and a bottom plate. The core plates are made of mild steel with a series of transverse slits in the centre. The damper mainly utilizes plastic bending deformation of the core plates to dissipate energy for vibration control of civil structures. Main performance parameters of the damper are studied through theoretical analysis. Mechanical properties of the damper are analyzed through finite element method (FEM). Finally, an experiment of the damper is conducted to verify the hysteresis performance of the damper. Results of the investigation indicate a better use of the core plates due to the transverse slits. The damper exhibits good energy dissipation capacity and ductility through the experiment.
